Understanding The Underlying Principles Of Cryptography In 3000 Words

1. Definition of Cryptography Before the late 20th century, cryptography was more of an art, primarily used for secret communication. At that time, there were no theories to rely on, nor any effective definitions to construct a good cipher. It wasn’t until the 1980s that the emergence of modern cryptography transformed the study of cryptography … Read more

Three Common Encryption Algorithms: MD5, Symmetric and Asymmetric Encryption

1. MD5 Encryption MD5 encryption characteristics: irreversible operation (cannot be cracked, cannot be decrypted) The result of encrypting different data is a fixed-length 32-character string (no matter how large the file is, it remains the same). The result of encrypting the same data is the same (that is, it is copied). Resistance to modification: the … Read more
